Product information

Description

The Rittal AS 4055.240 is a metallic-coloured round sheet metal punch designed for creating precise circular cut-outs in steel panels. It is intended for use where clean, repeatable Ø40.5 mm holes are required in control cabinets, enclosures, or similar sheet-metal installations.

Advantages

The tool provides a consistent round cut-out with a Ø40.5 mm diameter suitable for standardized fittings. Its metallic finish is durable and compatible with industrial environments. The product is compact and lightweight, making it easy to handle and position on steel sheets.

Suitable for

  • Punching Ø40.5 mm round holes in steel sheet metal
  • Creating apertures for cable glands, switches, or conduit fittings
  • Use on control cabinets, electrical enclosures, and panel work

When it may not be suitable

This punch is specifically sized for Ø40.5 mm round cut-outs and may not be appropriate when different hole diameters are required. It is designed for use on steel sheet metal; performance and suitability for other materials such as aluminum, stainless steel of high hardness, or plastics should be verified before use.

Key specifications

  • Colour: Metallic
  • Punch diameter (nominal): Ø40.5 mm
  • Weight (package): 554 g

How to use

Mark the desired hole centre on the steel panel and secure the sheet to prevent movement. Position the punch over the marked point and apply force according to the punch tool’s operating method (manual or press). After forming the hole, remove any sharp edges or burrs to ensure a clean aperture suitable for installing glands or fittings.

What to consider before purchase

  • Required hole diameter — this punch is for Ø40.5 mm cut-outs
  • Material compatibility — intended for steel sheet metal; check suitability for other materials
  • Mounting and operation method — confirm whether a manual or press-operated punch is needed

Usage recommendations

Use appropriate personal protective equipment and secure the workpiece before punching. Deburr edges after cutting to ensure safe and proper installation of components.
